i n Heretofore buttonshave been'V made which are secured to an object, such as anl article of f kwearing apparehbymeans of a tack driven into the button through-its hub and the point buttonyand also wherein the tack has been engagedl byf'an anvil within the button 'wlthi out upsetting or clinching the tack point.

The present invention relatesy to the second 10 mentioned type Of tack-fastened buttons, and

the invention, in the several figures of which like parts are simil-,arly designated, Figure l is a side' elevationofa buttonhead showing 25 one formof stabilizing means, and Fig. 2 is a similar view showinganotherform of stabilizing means. Fig'. 3 is a l'ongitudinalcrosssection of the button headof Fig. l with the l ,inserted tack-engagingv element or anvil and Va thumb-tack in position of entry thereinto arranged below it. `Fig. 4 is a longitudinal cross-section showing the button head of Fig. 2 and the inserted tack-engaging element or anvil. Fig. 5 is a view like Figf'with the tack. inserted and an interposed piece of fabric on which the button and tack are fasy tened. Fig. 6is atop plan view oftheytack-y lengaging element or anvil; yFigi is a bottom of the said element Or anvil. y

' As illustrating the invention Ihave shown a ,sheetmetal button headA of conventional shape, having a back l-,nmade integral with a hollowor tubularrhub 2,`and a cap or face plate 3 closed over, the rim of the back. The

hub is provided with af perforation i for the entrance yof the tackby which the button is attached to a object', 5, Figf, such as an to"` article of wearingapparel. The tack preferofthe tack upset Orjclinched within the.

base is coned upwardly with fthe apeXial end at lthe perforation 8, so that when thebutton tendency of the witl'idrawal of the tack. This plan view thereof, and 8 is an elevation in the buttonhole.
